TikTok Video & Image Sizes 2026: The Complete Size Guide

TikTok's entire interface is built around one shape: a full vertical screen. Post something in the wrong ratio and the app doesn't quietly adjust for you — it letterboxes your video with black bars, crops your carousel awkwardly, or buries your text behind the caption bar and action buttons. On a platform built for speed and instant reaction, a visibly wrong-sized post reads as amateur before anyone even gets to your content.

This guide covers every current TikTok size for 2026 — video, Photo Mode carousels, profile picture, cover images, and ad formats — cross-checked against multiple independently-published sources rather than any single guide, so you're getting numbers that actually agree with each other.

TikTok Sizes at a Glance (2026)

TikTok Video Size — The Core Spec

1080 x 1920 pixels, 9:16 aspect ratio is the standard across every content type on TikTok, and it's the one number that's genuinely consistent across every source. This matches the native portrait resolution of most modern smartphones, which is part of why filming directly in the TikTok app handles sizing automatically.

Recommended technical specs:

• Format: MP4 or MOV

• Codec: H.264 video, AAC audio

• Frame rate: 30fps for standard/talking content, 60fps for high-motion footage

• File size: roughly 287.6 MB on mobile upload (iOS and Android); up to 4 GB if uploading via TikTok Studio on desktop

Video length is the one figure worth treating with some caution. Most sources agree on a standard cap of 10 minutes (600 seconds) for the majority of accounts. Some more recent reporting suggests TikTok has been extending this — up to 60 minutes — for select newer or eligible accounts. Since this kind of platform-side rollout tends to happen gradually and account-by-account rather than all at once, the safest approach is to check the actual limit shown in your own TikTok Studio or app composer at upload time rather than relying on any single published number, including this one.

TikTok Photo Mode (Carousel) Size

TikTok's swipeable image carousel is called Photo Mode. It behaves differently from a video post in a few important ways:

• Image count: minimum of 4 images, maximum of 35 images per post

• Recommended dimensions: 1080 x 1920px (9:16), matching the full-screen vertical format

• Other supported ratios: 1:1 (square) and 4:5 (portrait) are technically accepted, but display with letterboxing — black bars — on the vertical mobile screen, which visibly signals the content wasn't designed for the platform

• File format: JPG recommended for photographs, PNG for graphics with text overlays

• Per-image file size: roughly 20 MB

If you only remember one number for TikTok carousels: design every slide at 1080 x 1920px, keep the count between 5 and 10 for engagement even though TikTok allows up to 35, and never mix aspect ratios within one carousel.

TikTok Carousel vs. Instagram Carousel — Don't Cross-Post Without Adjusting

If you're already building Instagram carousels (1080 x 1350px, 4:5, capped at 20 slides), it's tempting to reuse the same files for TikTok. Don't — the aspect ratios don't match. Instagram's 4:5 carousel dropped straight into TikTok's 9:16 frame will either crop awkwardly or letterbox with black bars. Build separately for each platform, or design a taller master file and crop down for Instagram rather than the other way around.

Safe Zones — Designing Around TikTok's Interface

TikTok overlays real interface elements on top of every post: the username and caption sit near the top and bottom of the screen, and the like/comment/share action buttons run down the right-hand side. Content placed too close to these areas gets visually crowded out or partially hidden, even though the underlying image or video technically isn't cropped.

As a practical rule: keep faces, text, and anything essential centered in the middle of the frame, away from the top strip, the bottom caption area, and the right-hand edge where the action buttons sit. Different sources cite slightly different exact pixel measurements for these zones, which suggests TikTok's UI has shifted over time rather than staying fixed — so treat "stay centered, avoid the edges" as the reliable rule, and preview your content in TikTok's own upload screen before publishing if you're placing anything close to those boundaries.

TikTok Profile Picture Size

This is one spec where sources genuinely don't agree, so here's the honest range: TikTok's stated minimum is 200 x 200 pixels, displayed as a circle throughout the app. However, several sources recommend uploading at 400 x 400px or larger, since the same profile photo gets rendered at multiple different sizes across TikTok — small in comment threads, slightly larger on the For You feed overlay, and largest on your profile page itself. A higher-resolution source file holds up better across all of those contexts than the bare minimum does.

Video Thumbnail / Cover Image

Your video's cover image uses the same 1080 x 1920px (9:16) dimensions as the video itself. The detail worth knowing: on your profile grid, where all your videos display in a 3-column layout, TikTok crops that cover down to roughly a 3:4 rectangle — meaning the very top and bottom of a full 9:16 cover can get trimmed in grid view, even though the full 9:16 image displays correctly when someone taps into the video itself. Keep any text or key visual centered vertically so it survives both crops.

TikTok Ad Sizes

Standard organic video specs apply as the baseline for most ad formats, but TikTok's ad review process is strict about exact ratio compliance — content that doesn't match 9:16 risks display issues or outright rejection in review, which wastes ad spend before the campaign even starts.

Common TikTok Sizing Mistakes

• Uploading horizontal or square video and letting it letterbox. This is the single most obvious "not built for this platform" signal on TikTok.

• Placing key text or a face inside the right-hand action-button column. It's a very easy overlay to forget about while designing off-platform.

• Assuming your Instagram carousel will work unchanged on TikTok. Different aspect ratio, different slide cap, different overlay zones — always adjust rather than reuse.

• Using the bare-minimum 200 x 200px profile picture. It'll pass, but a higher-resolution upload holds up visibly better once it's scaled up across the app's different display contexts.

• Overloading a Photo Mode carousel to the 35-image maximum. Multiple sources agree the actual engagement sweet spot is far lower — around 5 to 10 slides — since completion rate drops the longer a carousel runs.

Publishing to TikTok Without Re-Checking This Page Every Time

Getting TikTok's specs right once is manageable. Doing it consistently, on schedule, alongside everything else you're posting to Instagram, LinkedIn, and Threads, is where most teams start dropping details.

Treplino publishes directly to TikTok as one of its supported platforms, so your video and Photo Mode content go out already matched to TikTok's current dimensions — no separate export step, no manually re-checking a spec sheet before every upload.
